Abstract

The Purpose of our devise “Peripheral Intravenous Catheter With an internal Bi-Valvular Secure System” is to Avoid Back-flow spilling of blood or any other biological substance during the insertion of a catheter. Not only the Bi-valvular secure system is adaptable for the use in intravenous or arterial catheters but it can also be adapted to any type of Medical system catheters available in Medical practice due to its unique design, and without the need of changing the complete physical structure of the catheter. The present invention is for Medical field use and it provides a much more sterile and secure approach in reducing the risk of exposure to biological substances while at the same time reducing the risk of contamination to both the patient and the health care provider.

For Purpose of of describing the full operating system of our devise, we have to reiterate that its function is based on the concept of keeping a sterilized access to any Medical System Catheter by avoiding back-flow spilling of any biological substance that could increase the risk of exposure and contamination.

Description

The devise is an Adaptable Internal Bi-Valvular Secure System for Medical System Catheters as a hygienic method of containing back-flow secretion and blood spill from a peripheral IV or arterial line while maintaining a sterile peripheral IV or any other medical system catheter in the field and as well as in hospital setting.

FIELD OF INVENTION

The present Invention is for Medical Field use in the trauma or emergency setting, for any hospitalized or ambulatory treatment of any patient. It provides a more sterile and secure approach for peripheral intravenous insertion and any applicable catheter from peripheral and arterial lines, urinary catheters, central lines, ventricular catheters, and biopsy catheters (oncology) by avoiding unnecessary blood spill and the risk of back-flow contamination of biological substances and secretions.

SUMMERY OF THE INVENTION

For purpose of describing the full operating system of our devise, we have to reiterate that its function is based on the concept of keeping a sterilized access to the peripheral vein or arterial line, and to avoid unnecessary stress by the medic or trauma specialist do to constant blood spill once a peripheral or arterial line has been accessed, to keep a sterile access to any other applicable medical systems catheter in use and as well as for the patient, and, to reduce risk of contamination by back-flow spill of any type of biological substance fluid (blood, urine or secretions).
Our devise allows the Medical practitioner to insert any medical systems catheter without any back-flow of biological material and blood exposure that could complicate and compromise securing the catheter, the procedure and the access line.
Our intention is also to reduce the risk of contamination both to the patient and health care provider due to rapid manipulation in order to secure the catheter and/or peripheral line. It avoids putting the physician or paramedic at risk of contamination and reduces the risk of contaminating the patient. In the case where a peripheral line; whether it will be venous or arterial that needs to be accessed, our devise allows the health care provider to insert the peripheral line without any back-flow of blood that could complicate securing the catheter in a trauma like stressful scenario. This Bi-Valvular system will compose the internal structure of a peripheral IV or any other medical system catheter. The structural component of the valve are easy to ensemble at a very low cost due to the fabric of the system that is based on silicon rubber, plastic, and a stainless metal or teflon made spiral. The valvular system is adapted to the peripheral intravenous catheter at the level of the proximal end allowing a connection to the intravenous infusion line below the capping margin, and, allowing a two or three way stopcock to be connected and activating the sliding mechanism of the internalized valvular system. The internal Bi-valve secure system devise can be adapted to any catheter without having to change the structural components and physical shape of any medical systems catheter, only the invented devise will vary in size depending on the type of medical system catheter being displayed in use and allowing a secure connection and a two way flow of the catheter. Using a stopcock or syringe in order to administer or extract biological substance samples, once connected it will push the plastic or silicon sealing adapter located just below the capping margin adapting itself to the proximal portion of the plastic or silicon sealing adapter and sealing the connection (connection between the stopcock or syringe with the plastic or silicon sealing adapter), and at the same time activating the internalized valvular mechanism by pushing distally the plastic or silicon sealing adapter located in the proximal end of the plastic or stainless metal tube container guide and activating the sliding mechanism of the internalized plastic or stainless metal tube container guide. It is precisely from this tube container guide that the needle or guide wire from any medical system catheter is extracted. The role of an internalized plastic tube will as the component responsible to activate the sliding mechanism of the devise which is unique in its function by allowing the opening and closing of the silicon valve. This plastic or stainless metal tube guide will slide supported by the resistant function of the mini spiral band into and through a plastic guide located internally inside the body of the silicon rubber and functioning as the internal skeleton of the silicon valve component. As the plastic or stainless metal tube guide slides distally and in the same automatic fashion when removing the stopcock or any specific connection in between uses causing an automatic proximal retraction, it will open and close a Secure Bi-valve system allowing the access of fluids and medications or, the extraction of blood or any biological samples from any medical system catheter in use. When the stopcock or any other specific connection is removed in between uses, the plastic or silicon seal adapter attached in the proximal end of the tube guide retracts with the resistance support of the Teflon made or stainless metal mini spiral thus retracting the plastic or stainless steal tube guide by sliding proximally in a retroactive fashion through the internal skeleton of the silicon rubber valve and allowing the valve to close and seal automatically the access to the peripheral vein, arterial line or any other medical systems catheter being used for therapeutic reasons. The Teflon made or stainless mini spiral spring band allows the sliding mechanism of the valve to be activated with the appropriate resistance support when medications and/or fluids are administered, and to be deactivated when the IV, arterial line or any other medical system catheter is capped and closed in between uses. The plastic or stainless metal tube guide shelters the needle or guide wire used in any medical systems catheter, and, it is from this same plastic tube container that the needle or guide is retracted from. Unique in its function it allows the retraction and re-insertion of the needle and or guide wire if the need for relocating or re-inserting the catheter is necessary, and this function can be elaborated without damaging the bi-valvular structure and allowing complete manipulation of any type of system catheter. Our devise is activated when an external line is connected via stopcock or any other specific connection to the catheter by sealing to the plastic or silicon sealing adapter and pushing the plastic tube container located just below the capping margin and provoking a sliding mechanism using the teflon made or stainless metal made mini spiral spring band that works as resistance control component.
Through this sliding mechanism, the plastic or stainless metal tube container guide from which the needle or catheter guide wire is retracted from will slide distally through an internalized plastic skeleton centralized internally in the body of the rubber silicon valve and allowing it to push open the silicon valve. Through this same mechanism the plastic tube will be able to slide proximally retracting and closing the bi-valve. This will reduce exposure and risk of contamination in between uses.

Claims

1. Our invention is a unique valvular devise that is applicable to any medical systems catheter, it was specifically designed to avoid back flow of biological substances. The devise was first designed to be applicable to any simple peripheral line catheter with the idea of avoiding back flow spilling of blood whether be venous or arterial, but it is also a valvular design adaptable to any medical systems catheter without the advantage of not having to change the physical shape and components of any catheter. In the peripheral line catheters to which the Bi-valvular design was primitively inserted, the Bi-valvular system was adjusted perfectly into the central hub and automatically sealing the catheter by avoiding any escape, and converting the catheter into a closed system catheter with a unique Bi-valvular system that allows the easy extraction or removal of the needle or guide wire once the catheter is inserted and/or if needed the reinsertion of the needle or guide wire if manipulation and relocation of the catheter is needed. The advantage of this Bi-valvular devise is that the manipulation of the needle or guide wire will not damage the valve or impede its function. We claim the design of the valve as unique and one of its kind due to its simple composition and ability to fit and function as part of any Medical catheter system without having to change the conformity of the chosen catheter. Our devise has the ability to be integrated and built into the physical body and shape of any catheter system. It is logical to say and we are in our right to claim that this devise will only vary in size making it adaptable to any medical systems catheter applied to.

2. We claim the specifics of our Bi-valvular devise as a whole. The functional adaptability of the devise from its proximal structure to its distal structure work in conjunction and as mentioned in the specifications of the functional mechanism of the invention. The devise works by disengaging the accompanying needle or guide wire through removal. By extracting the needle or the guide wire once the catheter is inserted whether be a peripheral vein or arterial line, or any other medical system catheter the Bi-valvular system will close automatically creating a closed system catheter, and, with the unique ability of reinserting the needle or guide wire (considered pointy-cutting objects) without disrupting or damaging the Bi-valve and allowing the reopening and closure of the Bi-valvular system in case advanced or further manipulation or relocation of the catheter is needed. Once the needle or guide wire is extracted the catheter is inserted, the activation of the devise is through a unique sliding mechanism that is activated through an external connection. In this case we will describe the use of a two or three way stopcock or syringe in order to engage the valve. By externally connecting a two or three way stopcock or syringe to a medical system catheter, the devise located below the capping margin will seal through a plastic or silicon seal adapter allowing a two way flow from the external line into the peripheral. The connecting element of the stopcock or syringe to the capping portion of the catheter will not only seal to the plastic or silicon adapter, but it will push the adapter distally. The plastic or silicon seal adapter forms part of the proximal portion of the plastic made or stainless steal tube guide. This tube guide harbors the needle or guide wire and its from this tube guide that the needle or guide wire is extracted and reinserted. This plastic or stainless steal tube guide is surrounded in its trajectory from the base of the plastic/silicon seal adapter to the roof of the body of the silicon rubber valve by a Teflon made or stainless steal mini-spiral spring band that works as a resistance support for the tube guide during the sliding mechanism when externally activated by pushing the tube guide distally to open the valve, and in the same fashion sliding retraction of the tube guide when disengaging the valve by closing and creating a closed system catheter when the catheter is in between uses during therapeutic treatment of the patient. As the plastic or stainless steal made tube slides into the body of the silicon rubber valve, it does so through an internalized plastic tubular guide that functions as the internal skeleton of the body of the valve facilitating the slide through and opening of the Bi-valve from inside out, and in the same fashion facilitating the retracting mechanism of the tube guide to close the Bi-valve in between uses. The devise does not impede or reduce the free flow of therapeutic solutions.
